1. Create gps.conf file containing:
   

   NTP_SERVER=ru.pool.ntp.org
   XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
   XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
   XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
   SUPL_HOST=supl.google.com
   SUPL_PORT=7276

2. Copy gps.conf to SD card.
3. Run

   adb shell

   and type:
   

   su
   remount rw
   cat /sdcard/gps.conf > /system/etc/gps.conf
   reboot

4. After rebooting, your GPS initializes quickly.

Note that if you're not in Russia, you should probably use another server instead of the ru.pool.ntp.org, for example use :
NTP_SERVER=ro.pool.ntp.org for Romania
NTP_SERVER=hu.pool.ntp.org for Hungary
and so on.

I've tested with NTP Tool (a Windows utility) and I've got the following responses (RoundTrip Delays, lower is better) for the NTP servers (note that I'm in Romania)
north-america.pool.ntp.org = 0.25 - it seems that even the original 1.5 firmware had this setting (the 2.1 upgrade also has this server)
ru.pool.ntp.org = 0.093
hu.pool.ntp.org = 0.047
ro.pool.ntp.org = 0.001

So you can see that the closer the NTP server is to you the better the response time it is, so find one that's in your country.

Hi. I am Romanian, as well, but maybe people will find useful stuff so let's use English. Well, my problem is that GPS does not work at all most of the time. The strange thing is that (at this very moment) I have 13 satellites in view but it seems they refuse to connect. The odd thing is that if I am at the faculty, it works good enough (shows me as being in the next room). The building has only one floor and it is placed in a wide space without any blocks near it. But if I am in the middle of the street or at home, nothing happens. From home I managed only once to get some signal, half-hanging outside the window (I live at the very first floor - parter). Any idea on what I can do? I tried all the possible configurations of the gps.conf file and same results. I'm running fw 2.1-update 1 with SamdroidMod and Leshak's kernel (all up-to-date). Thanks.

I have the same issue. But it's not that satellites refuse to connect, since GPS device is only receiver. It's rather a problem with calculating fix. Another problem is that probably GPS accuracy is buggy. This makes whole GPS function buggy . I did reflash - tried on a clean JE4, SdM 2.05 and SdM 2.06b3 - always the same.
I observed, that first fix goes well (probably after phone reboot), but then it's getting worse. In GPS Status application I can see many grey columns (e.g.6-7), but no fix.
Additionally see this: http://forum.samdroid.net/f9/maps-na...-accuracy-1247

What worries me is that noone is looking at those issues

whow, has a massive effect in NL. thnx for this!

Just use fasterfix if you don't want to edit those files by yourself:

To the guys in Romania: what date/time settings do you have? Manually? If so, what timezone did you set? Or automatically?

[indraf]

for indonesia:

id.pool.ntp.org

or

asia.pool.ntp.org
